It focuses on preventing network loops using the spanning tree protocol.Study firgure $1$ below and answer the questions that follow. $1.$ Explain in detail how loops are caused in computer networks if the spanning tree protocol is not implemented. $6$ Marks

Using the information provided in figure $1$ answer the following questions:

a$)$Which switch will be elected as a root bridge. $2$ Marks

b$)$ Draw the network shown in figure $1$ and indicate how data communication will flow after the spanning tree protocol converges. $2$ Marks

c$)$ Explain the purpose of the priority number and MAC address in the selesction of a route bridge in spanning tree protocol. $6$ marks

d$)$ write down the command you would excute on Sw$2$ to make it a root bridge. $4$ Marks
